Consider the two-dimensional Poiseuille flow of Prob. 11–48. The fluid between the plates is water at 40°C. Let the gap height h =1.6 mm and the pressure gradient dP/dx = −230 N/m3 . Imagine a hydrogen bubble wire stretched vertically through the channel at x =0 (Fig. P11–52). The wire is pulsed on and off such that bubbles are produced periodically to create timelines. Five distinct timelines are generated at t = 0, 2.5, 5.0,7.5, and 10.0 s. Calculate and plot what these five timelines look like at time t = 12.5 s.
